Strange TCP/IP issue

[lyontl]

Hello,

I have a windows XP box that cannot access the internet. It is a completely new install on a formatted drive. After the install finished, no internet. Everything is set to the defaults. many other machines on the network can access the net with the same settings. This machine cannot. The strange thing is that when I ping say Yahoo.com I get an IP adress for it, but no response. If I do a tracert, it hits the server and stops. I CAN access all network resources, but not the internet.
Is there something on the w2k server that has to be cleared maybe?

Any help is greatly appreciated!

~Matt.

Is your DNS server pointed to an Internet host or an internal host?

I assume that you have run IPCONFIG /ALL and verified that configuration against your other machines.

Is the XP SP2 firewall enabled? You may want to disable while troubleshooting to eliminate that as a possible suspect.

Have you tried running Ethereal on the XP host so that you could verify that packets are indeed leaving the host and not returning?

If you ping other Internet hosts do their names resolve?

Can you ping hosts on your internal network?

Are you running Active Directory, and if so, do you have group policies set that might inhibit Internet communications?

Is your DNS server pointed to an Internet host or an internal host? I've tried both.

I assume that you have run IPCONFIG /ALL and verified that configuration against your other machines. Yes.

Is the XP SP2 firewall enabled? You may want to disable while troubleshooting to eliminate that as a possible suspect. No SP2 yet.

Have you tried running Ethereal on the XP host so that you could verify that packets are indeed leaving the host and not returning? I had never heard of that, so I didn't try it.

If you ping other Internet hosts do their names resolve? Yes.

Can you ping hosts on your internal network? Yes.

Are you running Active Directory, and if so, do you have group policies set that might inhibit Internet communications? It is a new client (as in customer) that I just got. It seems that this server has had many hands on it. I used a new box with a fresh install and a new name (therefore a new computer account) and it works fine. No time to resolve the issue, but thank you for the troubleshooting tips!

Do you have a Proxy server?

-------------------------------

If it doesn't leak oil it must be empty!!

Instead of Ethereal for a quick easy packet test
use pathping to an external address such as yahoo.com
type pathping yahoo.com
